Abstract
The invention relates to a device for constructing a laminar body from a plurality of superimposed layers of free-flowing material, in particular particulate material, and a build platform within a working area. The layers are solidified in locally predetermined regions by the action of binders and are joined together so that at least one moulded body is formed by the solidified and joined regions of the layers. The device comprises a discharging device movable back and forth over the working area in at least one discharge direction and having at least one discharge opening from which the free-flowing material can be discharged in individual superimposed layers during the movement of the discharging device.
Claims20
A method comprising:
- the steps of
- constructing an article from a plurality of superimposed layers of a free-flowing material, on a build platform within a build space, the layers being solidified and joined together in locally predetermined areas, including:
- applying the free-flowing material from a discharge device in layers, and selectively joining the free-flowing material;
- wherein the discharge device moves back and forth over the build space;
- wherein the discharge device is movable with respect to the stationary build platform;
- and
- adjusting the height of the discharge device relative to the stationary build platform;
- wherein the build platform has a build area and the build space employs a first portion of the build area and a second portion of the build area remains free of the free-flowing material.
